CALIFORNIA DEVICE FOR OPERATING CASE-MENTS, TRANSOMS, AND THE LIKE Application filed September 24, 1924. Serial No. 739,483.

This invention relates to devices for operating easements, transoms and the like, and has for an object the provision of a device which will ensure a proper closing of casements and the like and at the same time an even closing thereof. It often happens in the case of operators for transoms or easements that a portion thereof will not close evenly with a second portion thereof, as for instance in easements, the top portion of the window sash will not close evenly with the bottom portion, with the result that there is a sllght warp, and the present device overcomes this by suitable adjusting means.

A further object is the provision of operating mechanism of the above character which is easy to manufacture, novel as to structure, sightly in appearance and compact in construction, easy to manipulate and readlly adjustable.

With the above and other objects in View, the invention consists in the novel and useful provision, formation, construction, association and relative arrangement of parts, members and features, all as shown in certain embodiments in the accompanying drawings,

described generally and finally pointed out in claim.

In the drawings:

Figure 1 is an elevation of the easement incorporating the invention;

Figure 2 is a fragmentary elevation on an enlarged scale showing the operating means for the easement or transom or the like; Figure 3 is a fragmentary transverse sectional view on an enlarged scale and showing certain features of the operating mechanism;

Figures 4 and 5 are plan and sectional I views, respectively, of certain features of the operating mechanism;

Figures 6 and 7 are fragmentary cross sectional views on an enlarged scale of the adjusting means;

Figure 8 is a fragmentary cross sectional view on an enlarged scale and showing the method by which the operating means may be concealed in the sill; and,

Figure 9 is a modified form of structure 5 from the showing of a portion of Figure 3.

Corresponding parts in all the figures are designated by the same reference characters.

Referring with particularity to the drawings, we have shown at A a pair of casement windows a, and which casement window in each instance includes a sash member 1 enclosed within a frame 2, which frame has associated therewith the usual sill 3. The casement sashes are hinged to the frame as shown at 4 A frame or division member 4 divides the pair of easements a. The device for operating the easement or transom or the like, or in fact, the operating mechanism for the swinging closure is designated as an entirety by B, and the same primarily includes an opcrating shaft 6, a lever 0, adjustment means 0? associated with the shaft 1) and the lever e, a member 6 associated with the sash and with the lever e, and an operating -means f for the shaft b,all of which elements are used in practicing one embodiment of the invention. The operating means for the shaft 1) is detailed in Figs. 4 and 5 and the same includes a two-part casing 5, one part as 6 being formed to confine a gear 7'and worm 8, the teeth of which worm and gear intermesh as shown at 9. The shaft of the worm is given a squared opening as shown at 10 so that the end of a handle 11 may fit within such squared opening for the purpose of turning the worm. The hub of the gear 7 is given a square opening, as shown at 12, and such hub as shown in Fig. 5 is normally flush with the top and bottom surface members of such twopart casing. The casing is formed with 6X tensions as shown at 13 and 14 which are bored so that the same may be readily secured by suitable means such as shown at 15 to the sill as shown in Fig. 1 at 16 and 17. The shaft Z) is adapted to be received within the squared .opening 12 in the hub of the gear 7 and the shaft extends upwardly to where it is confined by a keeper 18 attached to the top frame member. It is thus evident as far as 5 the description has proceeded, that a rotation by the handle member 11 of the worm 8 will produce rotation of the gear 7 and likewise rotation of the shaft 6. Each member cl, of which there may be more than one, has asso- 10o elated therewith a lever 0, and such means (l includes a block formed with a bifurcated portion, the furcations of which are designated as and 21, and such furcations are slightly spaced apart at the zone marked 22 and are likewise formed with angularly cutawa or recessed portions 23 and 24. Such bloclf is formed with a screw-threaded transverse bore 25. An extension 26 is likewise formed on the block and such extension is adapted to be connected with the lever c. Said block is likewise formed with a transverse bore extending through the two furcations as shown at 27and 28 and a bolt member 29 is passed through such bore in the furcations with a nut carried by such bolt whereby the furcations can bed-rawn together. Adapted to. have screw-tln'eade-d engagement with the screw threads of the screw-threaded bore is a member 30, which membcr'is formed at 3'1 with an annular groove, and it is to be noted that the said member 30 projects in part within the recessed portions 23 and 24 of the furcations. Referenceto Figure 2 shows that any number of such adjustment means (Z and levers 0 may be used, and Fig. 1 shows a casement, using three of such members, all of them identical in formation. In each instance the adjustment means (Z is associated with the shaft: 6, and, Figs. 6 and 7 show that the shaft Z) is received within the recesses 23 and 24 and that such shaft is smaller than the cross sectional area included between the walls, surrounding the recesses 23 and 24. The member 30 is, really a screw provided with a central annular groove and such member can be adjusted inwardly or outwardly of the screw-threaded bore 25- by suitable means such as a screw-driver, the screw being provided with grooves 32 and 38 for this purpose, and when the shaft is, within the recessed portions 23 and 24, as shown in Figs. 6 and 7, it will be seen that two sid'eportionsof such shaft are received within the groove 31 and that adjustment of the member 30 inwardly or outwardly, in accordance with such figures willwedge the shaft against the block in different positions, thus causing a different angularity to-be assumed by the block with relation to such shaft. Thus, in the position shown in Fig. 6 the sides of the block d are approximately at right angles to a diagonal of such square shaft, while in Fig. 7 movement of the member 30 has changed such right angled position. The lever 0 includes a channel-shaped member, the legs 40, and 41 of which are formedwith spaced flanges 42- and 43respectively.v Adapted to be; received between the base portion 4401, such lever c, and the legs and flanges of such lever c, is a frictionmember 45, which member may include a leaf spring 46' curvedly bentas shown at 47, 48 and 49 so that the same, may frictionally engage the inner surfaces, of the legs and 41. The said leaf spring is carried in a suitable; casing 50 which is provided with cutaway portions to allow the spring portions 47, 48 and 49 to bear against the legs of the member c. The casing 50 in turn is fastened by means of a pin to a member 6 which is dapted to be secured to the casement sash. In this connection said member a has a part 61 which may be secured by screws or the like to the easement sash and a projecting part as 62 with said pin 60 secured to such projecting part.

In the showing of Figure 1 each casement a has secured to the sash portions thereof three of the members '0; that is to say, top and bottom members and intermediate member, and that there are three adjusting means (Z carryingle-vers cfor association with such members 0. The.operatingmeans f is secured to the sill, as shown at 16 and 17. Uponinserting the lever 11 within the squared opening of the worm shaft in the members f, rotation will be produced in the operating shaft 7) which will produce a simultaneous rotation of the levers 0 to open or close, the easements. If it should happen that the top of the casement did not close properly, .but left a slightly open space at the top thereof, while the bottom closed within the sill, the adjustn'ient of the member 30 inwardly of the showing of Figure 6, would move the lever c inwardly sov that the top would be properly closed. Such movement would be just the contrary of the movement shown for the member 30 in Figure 7. When the easement or transom has been properly adjusted it will at all times open or close properly without further attention, unless accident occur-to the same. Furthermore, when any swinging closure has been opened or closed or slightly opened, it is impossible to further open or close such swinging closure, due to the formation of the member f, the general principle of a worm and gear being well understood, and as the showing reveals the gear is mounted in connection with the shaft so any attempted turning of the shaft would produce a locking againstthe worm without any rotation- The adjustment feature of this device is of great importance, as any swinging closure can be adjusted so that it will at all times close properly. In Figure 8 the device f has been placed beneath the sill so that the same is not visible, and access to such device is obtained by boring the apron or trim so that the handle member may be received within the opening of the worm shaft. The shaft Z9" may likewise extend either exteriorly' or interiorl'y of the frame member with suitable slots formed in such frame so that the arms and adjusting mechanism may be readily accessible. In the showing of Figure 8', however, the shaft extends exterior the frame the same as in the showing of Figure 1, the said means. 7 being theonly part concealed.

In Figure 9 I have shown a slightly different form of the member 6 and which I designate g. In this instance the means 9 includes a part 80 adapted to be secured to the sash and a part 81 at right angles to such part 80, and such part is adapted to pivotally carry a member 82 provided with two spaced flanged rollers 83 and 84. Adapted to be received between such rollers and confined by 10 the flanges thereof, is an arm h, which arm in turn is secured to one of the adjusting means (Z. The lever h in the showing of Figure 9 is in the form of a rectangular bar and the sides thereof are in close working contact with such rollers 83 and 84. The function of the de ice as shown in Fig. 9 does not differ from that shown for the device 6.

It is obvious that various changes and modifications may be made in practicing the invention, in departure from the particular showing, without departing from the true spirit of the invention.

Having thus disclosed our invention, we claim and desire to secure by Letters Patent:

In a device of the character disclosed, a shaft, an arm, and means between the shaft and arm for regulating the position of such arm relative to such shaft; said means including a member formed with a recess within which the shaft is received, and means receivable in part within said recess for engagement with such shaft; such last named means comprising a screw formed with an annular groove, and such shaft in part being received within such annular groove.

In testimony whereof, we have signed our names to this specification.
